xlsfonts lists the fonts that match the given pattern.
The wildcard character "*" may be used to match any sequence of characters
(including none), and "?" to match any single character. If no pattern is
given, "*" is assumed.

The "*" and "?" characters must be quoted to prevent
them from being expanded by the shell.

Lists some attributes of the font on one line in addition to its name.

-ll

Lists font properties in addition to -l output.

-lll

Lists character
metrics in addition to -ll output.

-m

This option indicates that long listings
should also print the minimum and maximum bounds of each font.

-C

This option
indicates that listings should use multiple columns. This is the same as
-n 0.

-1

This option indicates that listings should use a single column. This
is the same as -n 1.

-w width

This option specifies the width in characters
that should be used in figuring out how many columns to print. The default
is 79.

-n columns

This option specifies the number of columns to use in
displaying the output. By default, it will attempt to fit as many columns
of font names into the number of character specified by -w width.

-u

This
option indicates that the output should be left unsorted.

-o

This option
indicates that xlsfonts should do an OpenFont (and QueryFont, if appropriate)
rather than a ListFonts. This is useful if ListFonts or ListFontsWithInfo
fail to list a known font (as is the case with some scaled font systems).
